What Tax Form 56 Does and when it matters

Tax Form 56, Notice Concerning Fiduciary Relationship, is the IRS form used to inform the Internal Revenue Service that a fiduciary has been appointed to represent an estate, trust, conservatorship, receiver, guardian, or other entity for tax purposes. Filing Form 56 notifies the IRS to direct communications, tax notices, and responsibilities to the appointed fiduciary and to help ensure that tax matters, refunds, and assessments are routed correctly. The form identifies the decedent or entity, the fiduciary, the type of relationship, and the effective date of appointment.

Why filing Form 56 is important

Filing Tax Form 56 formally establishes the fiduciary as the IRS contact for an estate or trust, ensuring that notices and tax obligations reach the person or entity authorized to act and reducing the risk of missed communications or incorrect assessments.

Why filing Form 56 is important

Who typically prepares and submits Form 56

The form is prepared when a fiduciary relationship is created and when the fiduciary needs IRS recognition to receive tax notices or to act on behalf of the taxpayer.

  • Appointed fiduciaries and executors responsible for estate tax administration and correspondence.
  • Tax professionals and enrolled agents preparing federal tax records and managing communications with the IRS.
  • Attorneys and guardians who manage estate or trust affairs and need official IRS recognition.

Timely submission preserves the fiduciary’s authority to receive IRS correspondence and reduces the chance of duplicate notices or incorrect liability assignment.

Primary roles that sign Form 56

Fiduciary

A fiduciary (executor, trustee, guardian, conservator) completes Form 56 to notify the IRS they are authorized to act. The fiduciary must provide identifying information and the effective appointment date so the IRS can route notices and communications appropriately.

Tax Professional

Certified public accountants, enrolled agents, or other tax preparers often prepare and file Form 56 on behalf of fiduciaries to ensure the details match tax returns and to confirm that IRS correspondence will be addressed to the correct representative.

  • Failing to update the IRS when the fiduciary changes can result in duplicate or conflicting notices.
